| Abstract: | LaCoste&;Romberg airborne gravimeter is the key equipment of the Chinese airborne gravimetry system. On the basis of the characters of the airborne gravimetry, the calibration method of the meter factor for the airborne gravimeter is discussed and the formula for computing the meter factor was derived. Thus,a new meter factor is determined using actual calibration data. The validation of the new meter factor is verified using the real airborne data from the Datong test. The results indicate that the systemic biases of the airborne gravity disturbance compared to ground reference can be reduced about 1×10 -5 ms -2 by use of the new meter factor. |
